ARM: 5960/1: ARM: perf-events: fix v7 event selection mask
The event selection mask for ARMv7 cores [ARMV7_EVTSEL_MASK]
is incorrectly set to 0x7f. This means that the top bit of an
event ID is ignored, so counting branch misses (id=0x10) and
ISBs (id=0x90) give the same results.
This patch sets the event selection mask to the correct value
of 0xff.
